Hey, I was wondering if the twin intake system (with the 2 360degree conical filters) sold by West Coast Corvette is the same as the RM Racing one people have here on this site? Also, will there '97-'00 Max Flow Mass Air Flow Sensor work on a 2004 corvette. Is this needed? I'm asking this becuase I have a friend willing to sell me his off his 2000 vert for a couple hundred bucks, vs. the $500+ he spent with them a few years ago.... Thanks everyone!
